Abstract:
A storage container for cryogenic liquids has an outer container and at least one inner container, an insulation space being situated between the outer container and the inner container or containers. The outer container and/or the inner container have devices for strengthening the container walls. The devices for strengthening the container wall of the outer container and/or of the inner container are constructed as at least one web arranged on the container wall of the outer container and/or of the inner container and/or as at least one supporting plate adapted essentially to the cross-section of the inner container.
Abstract:
A buried fluid storage tank with a single fluid-tight enclosure which comprises an external concrete enclosure buried into the ground, a rigid structure with a bottom slab and possibly a covering dome as well as a fluid-tight heat-insulating envelope which defines inside of the structure a fluid loading space, whereas the external enclosure has the shape of a thick substantially fluid-tight wall, this enclosure as well as the covering dome being made integral with each other from one single piece of material and forming together with the bottom slab the stiffening structure of the tank, the invention being applicable to a confinement tank in particular for a harbor terminal for loading a liquefied natural gas.
Abstract:
A ceramic fiber fabric such as an alumino-boro-silicate fabric is impregnated with a silicone elastomer to form a composite material. The fabric may be reinforced with hoops or rings to provide a free-standing insulation. The insulation is attached to the wall of a tank. The tank may be subjected to cryogenic temperatures such as during a cryostretch tank formation procedure, without cracking or spalling the insulation. The insulated tank can withstand exposure of elevated temperatures such as about 2000.degree. F.
Abstract:
A high pressure vessel assembly includes a central pivot tank and coaxial or concentrically disposed tanks for liquid or gas storage with or without gaseous phase cooling. The pivot tank comprises a cylindrically shaped wall having torus-shaped ends and is surrounded by an annularly shaped internal tank having internal and external walls with the former being joined to the pivot tank by bands adjacent the tank ends to provide an intermediate chamber. A larger diameter external tank likewise of annular configuration, surrounds the internal tank and is also joined thereto in a manner providing an intermediate chamber. A fitting projecting from the ends of all three tanks at one end of the assembly permits filling or emptying of the respective tanks while a separate discharge pipe projecting from the internal and external tank ends communicates with the two chambers to carry away any fluid leaking from the juxtaposed peripheral walls of the tanks.
Abstract:
A pressure-resistant container for liquids, gases, or loose material is composed of at least two part-cylindrical shells which have mutually parallel axes and intersect each other so as to form troughs between the tops and bottom thereof, respectively. In accordance with a preferred embodiment, the ends of the part-cylindrical shells are joined at their edges along the height of the longitudinal troughs formed between the tops and bottoms of the part-cylindrical shells of the container by their intersection, whereby a central shell element forms tunnels respectively interconnecting the tops and bottoms of the part-cylindrical shells.
Abstract:
Vaporizing a liquefied gas by feeding the hot products of combustion of a combustible material into and below the surface of a mass of the liquefied gas in a tank, said liquefied gas being at a temperature at which at least water in the hot products of combustion is solidified, removing from the tank unsolidified products of combustion in admixture with the vaporized gas formed by heat exchange between the hot products of combustion and the liquefied gas and at least periodically removing from the tank solidified water.
Abstract:
924,803. Storing liquefied gas. CONCH INTERNATIONAL METHANE Ltd. June 20, 1961, No. 22193/61. Class 8(2). A tank for liquefied gas, e.g. natural gas, nitrogen or helium, comprises a container constructed of dimpled, thin metal sheets surrounded by and supported on load-bearing surfaces which are part of a thermal insulation system, spaces between the outside of the dimples and the load-bearing surfaces being filled with a resilient filler, e.g. polyurethanes and polyvinyl chlorides, particularly of the foamed type, or resin bonded fibres such as glass fibres. As described a prismatic tank has a floor 9 and side walls 7 formed from dimpled stainless steel sheet fixed at 10 and 8, respectively, to plywood panels 5 and 4 which with further plywood panels 6 and 3 are bonded to balsa wood panels 2 and 1 of the insulation system. The corners between the floor and side walls are sealed by gutter-like, transversely corrugated strips 11. The resilient filler is shown as 13 between the floor and side walls 9 and 7 and the plywood panels 6 and 3. The space between the strips 11 and the panels 4 and 5 may also be filled with reslient filler. The metal sheet may, alternatively, be made of aluminium or its alloys or copper or its alloys and the thermal insulation may be quippo, cork, foamed plastics, glass, asbestos, jute fibres, mineral wool or cellular gypsum. The metal sheet may form a barrier round another vessel for the liquefied gas to prevent escape of the gas in case of rupture of that vessel; the dimples on the inside of metal sheet may in this case also be filled with resilient filler. Specifications 919,587, 924,801, 924,802 and 924,804 are referred to.
